Hypoxia‐induced vulnerability of the somatosensory nervous system
The Journal of Physiology, EarlyView.Abstract figure legend Sensory neurons are highly energy dependent and rely on sufficient oxygen availability to maintain metabolic stability and effective neurocommunication. Within the somatosensory system, even modest reductions in tissue oxygen tension impair neuronal respiration, forcing a shift toward less efficient metabolic pathways that ...

A Revised Model for Muscarine Biosynthesis Involving Lysine Trimethylation
Angewandte Chemie, Volume 138, Issue 24, 8 June 2026.The fatal mushroom toxin l‐(+)‐muscarine is one of the most prominent natural products. We elucidated its biosynthetic origin in the sweating mushroom Collybia rivulosa based on incorporation of stable isotope‐labeled compounds and extensive mass spectrometric analyses.

Alliinase: A Comprehensive Review of the Pivotal Enzyme in Garlic Chemistry and Its Applications
Food Frontiers, Volume 7, Issue 4, July 2026.Garlic crude extract was purified to obtain alliinase, which catalyzes alliin hydrolysis to release allicin. The free and immobilized alliinase shows potential applications in food, biotechnology, pharmaceuticals, health products, and biosensors. ABSTRACT Alliinase is a pyridoxal 5′‐phosphate (PLP)‐dependent lyase that serves as the cornerstone of the ...

Vitamin‐Responsive Disorders: From Molecular Basis to Clinical Presentation and Therapy
Journal of Inherited Metabolic Disease, Volume 49, Issue 4, July 2026.ABSTRACT Vitamin‐dependent cofactors are essential for numerous metabolic reactions, and defects affecting their uptake, conversion, utilisation, or regeneration constitute a heterogeneous group of inherited metabolic disorders (IMDs). Although dietary vitamin intake is sufficient to sustain coenzyme synthesis in healthy individuals, it is insufficient

Journal of Inherited Metabolic Disease, Volume 49, Issue 4, July 2026.This study shows that methionine synthase (MS) interacts with MATα2, responsible for SAM production, and the methyltransferase DNMT3b in the nucleus. These results support the idea that spatial compartmentalization of one‐carbon metabolism could play a major role in regulating the epigenome.

Delay in Diagnosis of Classical Homocystinuria
JIMD Reports, Volume 67, Issue 4, July 2026.ABSTRACT Classical homocystinuria (HCU) is an autosomal recessive disorder of methionine metabolism with a wide spectrum of severity and clinical presentation. Timely diagnosis facilitates prompt initiation of treatment, which reduces complications. Our aim was to identify the nature of the first clinical manifestation and time to subsequent diagnosis ...
